Almond Flavored Icing

I have a customer that has requested almond icing. I've never made it before. Can I just substitute almond extract for the butter flavoring or vanilla flavoring in my usual buttercream recipe? I appreciate any help, thanks!

Almond extract can be quite strong, so I would maybe do half of the vanilla and see how it tastes. If you want it stronger, just add a little bit more. I think you could probably keep the butter flavour extract in there.
